Final answer:
The deflection of a ridge beam refers to its bending or sagging under load, and can be calculated using the Euler-Bernoulli beam theory. The deflection is measured as the vertical displacement of the beam at its midpoint.
Step-by-step explanation:
The deflection of a ridge beam refers to its bending or sagging under load. It is typically measured in terms of the vertical displacement of the beam at its midpoint. The deflection of a ridge beam can be determined using the appropriate beam deflection formula, which takes into account the beam's material properties, dimensions, and the applied load.
One commonly used formula to calculate the deflection of a ridge beam is the Euler-Bernoulli beam theory. This formula considers the beam as a slender rod subjected to axial, bending, and shear forces. It can be used to calculate the maximum deflection based on the beam's span length, material modulus of elasticity, moment of inertia, and the applied load.
For example, if a ridge beam has a span length of 20 feet, a modulus of elasticity of 30,000,000 psi, a moment of inertia of 1000 in^4, and an applied load of 2000 pounds, you can use the Euler-Bernoulli beam theory to calculate the deflection.
